GMap subgurim.net仅显示灰色框

Question

this is my code, taking latitude and longitude from database and showing to gmap tool. Its running without any error and i can see the data also getting correct, but not showing any map on the display only grey box with powered by subgurim window. do i need to add anything else with this to see the maps.

  GLatLng mainLocation = new GLatLng(20.300000099999997, 50.4000000); GMap1.setCenter(mainLocation, 15); XPinLetter xpinLetter = new XPinLetter(PinShapes.pin_star, "S", Color.Blue, Color.White, Color.Chocolate); GMap1.Add(new GMarker(mainLocation, new GMarkerOptions(new GIcon(xpinLetter.ToString(), xpinLetter.Shadow())))); GeoLocationDB objLocationDB = new GeoLocationDB(); GeoLocationList objLocationList = new GeoLocationList(); DateTime dt1 = new DateTime(); dt1 = new DateTime(Convert.ToInt32(txtDatePicker.Text.Split('/')[2].ToString()), Convert.ToInt32(txtDatePicker.Text.Split('/')[1].ToString()), Convert.ToInt32(txtDatePicker.Text.Split('/')[0].ToString())); DateTime dt2 = new DateTime(); dt2 = new DateTime(Convert.ToInt32(txtDatePicker1.Text.Split('/')[2].ToString()), Convert.ToInt32(txtDatePicker1.Text.Split('/')[1].ToString()), Convert.ToInt32(txtDatePicker1.Text.Split('/')[0].ToString())); objLocationList = objLocationDB.GetListBySearch(txtStaff.Text,dt1,dt2); PinIcon p; GMarker gm; GInfoWindow win; foreach (var i in objLocationList) { p = new PinIcon(PinIcons.car, Color.Cyan); gm = new GMarker(new GLatLng(i.Longitude), new GMarkerOptions(new GIcon(p.ToString(), p.Shadow()))); win = new GInfoWindow(gm, i.ShopName + " <a href='" + i.Address + "'>Address...</a>", false, GListener.Event.mouseover); GMap1.Add(win); } 

Please help me to find solution. thanks in advance.

Answer 1

I was supplying only latitude , but the data was both latitude and longitude. change the code to below working fine now.

  GLatLng mainLocation = new GLatLng(20.300000099999997, 50.4000000); GMap1.setCenter(mainLocation, 15); XPinLetter xpinLetter = new XPinLetter(PinShapes.pin_star, "S", Color.Blue, Color.White, Color.Chocolate); GMap1.Add(new GMarker(mainLocation, new GMarkerOptions(new GIcon(xpinLetter.ToString(), xpinLetter.Shadow())))); GMap1.addControl(new GControl(GControl.preBuilt.GOverviewMapControl)); GMap1.addControl(new GControl(GControl.preBuilt.LargeMapControl)); GeoLocationDB objLocationDB = new GeoLocationDB(); GeoLocationList objLocationList = new GeoLocationList(); DateTime dt1 = new DateTime(); dt1 = new DateTime(Convert.ToInt32(txtDatePicker.Text.Split('/')[2].ToString()), Convert.ToInt32(txtDatePicker.Text.Split('/')[1].ToString()), Convert.ToInt32(txtDatePicker.Text.Split('/')[0].ToString())); DateTime dt2 = new DateTime(); dt2 = new DateTime(Convert.ToInt32(txtDatePicker1.Text.Split('/')[2].ToString()), Convert.ToInt32(txtDatePicker1.Text.Split('/')[1].ToString()), Convert.ToInt32(txtDatePicker1.Text.Split('/')[0].ToString())); objLocationList = objLocationDB.GetListBySearch(txtStaff.Text, dt1, dt2); PinIcon p; GMarker gm; GInfoWindow win; foreach (var i in objLocationList) { p = new PinIcon(PinIcons.car, Color.Cyan); string str = i.Latitude; string[] values = str.Split(','); for (int s = 0; s < 1; s++) { double lang =Convert.ToDouble(values[0].Trim()); double longi = Convert.ToDouble(values[1].Trim()); gm = new GMarker(new GLatLng(lang,longi), new GMarkerOptions(new GIcon(p.ToString(), p.Shadow()))); win = new GInfoWindow(gm, i.ShopName + " <a href='" + i.Address + "'>Address...</a>", false, GListener.Event.mouseover); GMap1.Add(win); } } 

Same time i put the key to html code also.

 <cc1:GMap ID="GMap1" runat="server" Width="600px" Height="500px" enableHookMouseWheelToZoom="True" mapType="MapMaker_Normal" Key="abcd"
